To link coil 89 in order pulling down, at first, extracting tool 90 to be moved to the top, will link coil 89 and be contained in the resettlement section 91, and between adjacent coil insertion claw 92.
Then, shown in Fig. 6 (B), make spool 2 retreat and it is housed in the cylinder element 8.At this moment,, therefore, can link coil 89 certainly and extract spools 2 out, link coil 89 and be disassembled instrument 90 maintenances because binding coil 89 is moved by claw 92 restrictions.
Then, shown in Fig. 6 (C), will discharge rod 93 be inserted into link in the coil 89 after, make extracting tool 90 declines and turn back to original position.Thus, link coil 89 and be discharged from rod 93 maintenances.
Then, shown in Fig. 6 (D), make to link coil 89 and move to and discharge case 94 tops, make and discharge that rod 93 is retreated and, link coil 89 and drop to and discharge in the case 94 thereby make with its extraction.As above ground will link coil 89 be recovered to the discharge case 94 in.
Link coil 89 and be arranged as three-phase coil, between the adjacent coil of a phase, dispose the coil of other two phases and form the linear motor coil.Internal configurations at the linear motor coil has mobile members such as permanent magnet, and this mobile member responds the excitation of linear motor coil and moves.
Adopt above the 1st execution mode, play effect as follows.
What be wound with wire rod 1 only is spool 2, can utilize that a spool 2 makes that a plurality of coils link the binding coil.Like this and since not need with the corresponding reeler of coil number that links coil, therefore, the structure of Winder can be not extensive, complicated, can make easy structure.
In addition, the coiling width of each coil of formation binding coil is limited by the end face 8b of the end face 24a of chuck 24 and cylinder element 8.That is,, therefore, can suppress the deviation of the coiling width between each coil because the coiling width of each coil can utilize shared member to adjust.
In addition, in this execution mode, not the method for winding that makes nozzle flywheel-type of rotation around reeler; But make the method that will be wound the line by spool 2 rotations of wound skein product; Therefore, can in wire rod 1, not produce and reverse, can stably wind the line.
And, because the structure of coil-winding device 100 is easy, therefore can hot air apparatus 83 be configured near the position of spool 2, therefore, can make the molten deposited state of each coil even.
